Abstract

A central speaker and personal headset speakers are used to create a three-dimensional phantom sound space for each listener. The speakers of the headset are located in close proximity to, but do not isolate, the ears of the listener such that external sounds are allowed to impinge upon the pinna of the ears. The headset speakers form an isosceles triangle with the distant central speaker as the apex. This speaker configuration with personal controls can achieve a state of sound equilibrium for a phantom three-dimensional sound space. The sound signal may be synchronized with a video signal, and the sound pressure level of the left and right speakers can be adjusted to control the listener's perception of the virtual movement of phantom sound source image within the sound space according to changes in the point of view represented in a displayed video image.

Description

[0001] This application claims the benefit of U.S. Provisional Application No. 60 / 607,358 filed on Sep. 3, 2004, the contents of which are hereby incorporated by reference in their entirety.FIELD OF THE INVENTION

[0002] The present invention relates in general to a sound reproduction system, and, more particularly, to a system for producing a three-dimensional sound space. BACKGROUND OF THE INVENTION

[0003] Prior sound reproduction systems attempted to reproduce the audio realism of three-dimensional spaciousness through the application of sophisticated electronic technology to virtualize the third dimension of sounds or to form immersive sound fields with multichannel surround sound formats. However, this can be costly with limited effectiveness, and the realism of three-dimensionality of sound is left partly to the listener's imagination as to what is being heard and what is intended to be heard.

[0004] Multi-speaker formats, such as a 5.1 speaker set-up, are well known for creati...
